A Newer, Faster Ocean (The Problem is Godzilla)

I've been corralled by a friend of mine to write a myth story relating to the ocean, for use by her band, which is working on an album drenched in ocean themes.  Something involving creatures of the deep: giant squid, Kraken, octopus, or some such.  I'm certainly flattered by the idea that someone would turn to me for myth, and the project is exciting to me.  And yet I'm stumped and flustered.  I have so many ideas about it that I don't know how to choose, how to narrow things down to just one story.

I've settled on the idea that it should be something contemporary: a story of a sea monster which feeds on the plastic and other waste we dump into the sea every day, or something along those lines.  There are so many possibilities for mutation in this day and age that it's hard to pinpoint exactly which thread to follow.  The problem is Godzilla.  Particularly given the recent/ongoing Japanese nuclear reactor disaster, which is resulting in massive quantities of radioactive material pouring into the ocean, it's hard to imagine a fate for the seas which doesn't involve mutated monsters rising from the waters to crush a modern metropolis in revenge for the damage we've done.  Perhaps this is the most likely scenario.  Godzilla therefore becomes less myth and more speculative fiction.  He/it is too obvious, too predictable in response to the current ecological scenario, and therefore loses power as a basis for myth.

Perhaps, rather than a mutation myth, the story should involve an endangered animal and its struggle for survival then.  A last-of-its-kind adventure, a navigation of the perils of the 21st-century ocean: the pollutions, ecosystem devastations, and pollutions we conveniently can't penetrate the water's edge to see.  A kind of overcoming, uplifting but sad.  The last of its kind, alone, destined to fade into memory or be forgotten completely.  But therefore poignant, taking in the small details with an urgency that's lacking from our day-to-day lives, which we assume will carry over into another day, another year, another generation.  When the existence of an entire species is on the line, the stakes of each and every moment are magnified.

So perhaps this is the answer.  The specifics will come out in the end.  A rethinking of the ocean itself is central though, I think.  As our society accelerates and digitizes, becomes more and more borne on the light arrays and digitized wireless signals that carry the tiniest particulars of our worlds everywhere, the ocean, itself a medium for information, travel, life, keeps pace.  What does it mean to have a faster ocean?  That is the next question to ponder, one that I think will help me to see my myth more clearly.  I think my creature will have to adapt to this accelerated environment in order to survive, and thus will become something fundamentally different, something unique and greater than it was.
